in iont'f the keyboard l() of en Under Wood typew'iting machine 11 is a row of CIK pnennetm column .stop keys 1Q, eecliin the ioiin of e collapsible soft rubber bul-b. Each onli is provided on 'its rear end with an elbow shaped tube 13, which bende downwmclly below the typewriter frame, and teinlinetes in a nipple 14, over which is caught t-lie end oie flexible rubber tube or conclut,

which' extends reniwaidlyet ll'eneath the".

machine, engl is supported' by e rack or Tuer-d 16 secured upon the bottom of the 'traine et 'lts rear end the -tjube :extengllng thence naweitily in of the mziliine e at l?, anfl caught Aover a nipple i8 prollecb ing ieaiwarclly from a stop carrier 19. A ypiston is littefi in a bore 2l of the stop carrier, and terminates in a forwardly eX- tending shank 22 which constitutes the column stop prop'er.

At Fig. ,el the operators linger is shown as having collapselone oi' the eys or bulbs 12, to drive the air through the lube if, l?, to force forwardly the piston 20 from the piston-stop 18a, andr project the stop 22, as at Fig. 7; in which position the stop is in the path of the usual pendent slop or lug 23 providefl npon the paper carriage 2l, whereby the carriage may be arreste. after rainning tlie desireil distance.

Each' of tbe'carriers 19 resembles generally .the usual column stop device 'of an Unelerwoocl typewriter having a tooth or teeth. 25 to engage a rac 25, and also having a perforation 2'? to enable it to fit loosely upon aro- 28; and also provided with a handle 29, whereby the carrier may be turned backwardly about the rod to release the tooth 25 from the rack 26, to adjust the carrier along tile rack; the rack having a scale 80 and the carrier having an index 3 A spring datent or ball 32 engages a groove 33 in the rod 28, to liolfi the carrier in engagement with the rack 26. Flexibility of the tube or connection 17 permits adjustment of the carrier 19 along the raclz 26 as fai as desired.

The carriage -524i is drawn along upon a rail 3e by means of a spring (not shown) and has a rack in mesh with a pinion 36,

. the latLl r formino part of the usual escape- A mounted ciiiectl ment devices. Tee rack is llingeil upon a pair of arms 37, so that it may be lifted from tlie pinion 36, to permit the carriage to run along ireely under the driving power 'of its s Iring. 'A releasing lever 38, Fig. 2, is usually pivotefl at 39 upon the frame Work, anti carries a roll el), whereby it, may liittlie rack 35. This lever 38 is usually 'operated in said machine by an am 4l i'iaecl upon a rock shaft 42. Arms i3 are romachine, and connected by endent links ,44 with a air of levers lfulbrumed at i6 uponthe iiiameworlr, and carrying at their forward ends a transverse bar e7.; tie-rofis i8 connecting the levers 45 to forni a clepressible frame. The pneumatic lieys i2 ai' upon the bei' et?, anti the latter may be epiessecl citlier bv pressaa upon any bulb l2, as at l, or w'ithou touching any bulb; movement being transu` mittefi through tbe described connections to the rack 35 to lifty the same from tbe escapement pinion 36. The carriage may thus be released to run until the engagement of the carriage stop or lug 28 with that column stop 22 which has been projected by the flepressed pneumatic liey 12.

arrasa-a lt Will be noted that as usual in the Um v dervvood machine the rack 26 is secured upon arms 49 which extend. up from the carriageaeleasing rock-shaft 42, so thatv said rack 26 together with tile rod 28 vibrates forward to theworlfing position at Fig. 3V simultaneously with the projection of the column stop and the releasevof the carriage; and upon release of the key 12, said rack falls idly back to the Fig. 6 position. The suction in the .tube 17 draws back piston 2G a nst internal stop-pin 18a. The stoppin l 1s placed Within the nipple the piston 20, during its back stroke, from 'reaching- 1; the end of said nipple.

A spring 59, Fig. 6, returns the release key or bar 47 to norma-l position, and il; 'has sncienttension to. prevent saicll bar. e?

from being depressed, without first. collapsing one -of the bulbs l2 uponsai balg'so that the Vstop22 musi; be set before the carriage is released.

A. scale 5l may be placed immediately back of the keys 12, and suitably marked to enable tlieoperator to select readily the pro er key for arresting the carriage.

ariations may be resorted to within the scope oi' the invention, and portions of the improvements may be used without others. lfiaving thus described my invention, l can l.
